But it only came once, several reboots after that were ok. I changed my kernel config today: e1000 is now "=y" (was "=m"), I removed PCMCIA as I do not use it and some other modules complained about it, and I added CONFIG_HIGHMEM4G=y (was CONFIG_NOHIGHMEM=y)
The running kernel is 2.6.22.5 +cfs +squashfs. My distribution is gentoo (x86), quite up to date, udev is 104-r12.
